PAPER-MAKING MACHINE.

Specification of Letters Patent.

Application filed March 27, 1912. Serial No. 688,708.

To all whom, it majconcern: Be it known. that we, JOHN W. KOOKEN and JOHN H-i-REEDY, citizens of the United States, residing at Hamilton, Butler county, Ohio, have invented'certain newanduseful Improvements in Paper-Making Machines, of which the following is a specification:

This invention pertains toimprovements' =n Fourdrinier paper making machines, the

improvements being 1 designed to avoid the formation, in damaglng quantities,of foam at the'head of the wire. It often happens in the working of the Fourdrinier machine,- that large quantities of foam form on the a ron and wire between the flow-box and' t e slice, this foam being detrimental to nice flow of properly conditioned pulp as the i a .Fourdrinier machine "provided with an exemplification of our improvements, all de'ckle work being omitted; Fig.2 a plan ofthe same; Fig. 3 a plan of the clutch, Fig. 4 a vertical transverse section of the ray-pipe and one of "the ,spraying ,noz z es; and Fig. 5 a front elevation of the por- :tion of this spray-pipe.

In'the drawing :-.1, indicates the breastroll of a. Fourdrinier machine; 2', the wire thereon; 3, the slices; 4, thefloW-box; 5, the

apron-board 6, the apron, allof the parts thus far referred to being .ofus'ual construction and subject to usualm'odificati'ons; 7,brackets' supporting bearingsfor'aspray in thesebrackets; 9, down'war ly 1 e extendingcacross the machine,: these rgckets being'illustrated as secured to the top of the side walls of the flow-box; 8, a pi e mounted r0jecting spray-nozzles disposed at .intervalis along the 's ray-pipe and adapted to deliver downing the arm upon the spray-pipe in selective war ly 'spraysfof um rella. character, the

particular construction of these nozzles being "immaterial; 10, a fixed water-supply pipehaving-swiveled connection with one end 'of the spray-pipe; 11,. a slotted arm clamped to the spray-pipe near one of its ends; 12, a'clamp-screw to serve inclampangular osit-ion relative to theradial proectio'n o :the nozzles from the spray-pipe; 13, a crank of adjustable stroke supported by fixed bearings at the side of the machine beldw the sprayipe; '14, a sprocket-wheel connected with t e crank; 15, a sprocketwheel loose on the projectin of the journals of "connecting the two sprocket-wheels; 17, a linkconnecting arm ll'and crank'13; and

.18, a clutch, of obvious character, adapted to lock sprocket-wheel 15 to the journal' of the breast-roll.

' In the ordinar o eration of'the Fourdrinier machine t e 0am tends to form on Patented Apr. 22, 1913.

g end of one the breast-r0 l; 16, a chain the a ron-and -wire between the flow=box and t e first slice and, with some characters of pulp, this foamtends'to build up-to an enormous. de th. Attempts have been made to get rid 0 this foam'by thro'wingietsbf water downupon it and by blowing air pon it at some selected point, but withsomec aractors of [pulp it has been found impossible fto keep down thefoaln formation satisfactor'ily. Y t t In our construction, assume clutch 18 to t be disconnected, as in.,Fig..3, and assume the machine tobe in operation and assume that water is. being delivered to the spray-pipe by 'su plypipe 10L. A' number of umbrella shape q-sprays will manifestly bedeli'vered upon the pu p the foam and with certain kinds of pulp largeiquantities of foam may. bank u on the apronbehind the first slice. The c utch as it leaves the flow-box and goes to the apron. This will not keep down is-now; to be connected, as indicated in Fig.1

2, whereupon, through the medium of the s rocket-wheels and chain. andpcrank and 11111: and slotted arm,'the spray-pipe isgiven;

an oscillating motion whereby the"conicalc sprays,1while delivered in a general down ward direction, swee I tween the slice and t e flow box, theresult back and'Tfo'rth'Ube being, under proper conditi'ons'of iadjh t; y

ment'for the. sweepingmotions of the spra s, y the prevention of theformationof 'foainfto anydainaging'extent. Byfadjnstmentbf the 1 throw "of crank 13 the amplitude"ofthe sweeping motion of the. sprays may'ybe yadj-f ice just-ed, and a similaradju'stment foramp1i'-. 1 tude of spray-sweep may be-efl'ectedby' 'ad'- justingfthe llnk-wrlst in the slotted arm;11.' I

Clampscrew 12 may be loosened" and the nozzles given a selected angular relationship to the slotted arm and, when 'theclampscrew is again tightened the field of action of the sweeping sprays will have been" altered. By such means the sprays may be given short or long sweeping motions and the field of their sweeping action may extend from the first slice to Well within the flow-box or it may be restricted to such point as-best' serves in keeping down the foam.

It is desirable that the spraying nozzles be of such adjustable character that the thickness-of .:the wall of the spray-may be adv justable, Fig. 4 illustrating a typical form of adjustable nozzle, the thickness of the annular sheet of water forming the spray being adjusted by setting a cone farther into and out of a conical dehveringnozzle.
